IMPROVEMENT IN ADJUSTABLE TRACK FOR CONVEYING LOADS BY GRAVITY ONLY.

TO WHOM IT MAY CONCERN: I

Be it known that I, Avon W. ORAMER, of Bethany, in the countyof Wayne,and State of Pennsylvania,

declare that the following is a full, clear, and exact description ofthe same, reference being had to the annexed drawings, making part ofthis specification, in which- Figure 1 is a perspective view. Y

Figure 2 is a vertical longitudinal section.

The same letters are employed in all the figures in the indication ofidentical parts.

This invention consists in the attaehment between two points ofsuspension of a wire or rope so arranged and in placing upon the trackthus formed a carriage, which, with the alternations in the inclinationof the rope, will traverse it in alternate directions, carrying with itarload, to be deposited at any intermediate point, as desired. D Y i Aand A are two posts, representing the points of attachment of the endsof the wire or rope B, which is firmly andpermanently secured at oneend. The other endis carried over a sheave, C, and thence around theaxleD, which may be turned by the winch E or by gearing. F is an eye,through which passes the rope or wire B, the eye being large enonghtotravel freely upon the wire. G is a cord connecting the eye F with theaxle D, and so wound around the same in the direction opposite to thecoil of therope or wire B, that, as one is wound upon the axle, theother will be unwound. Thus, as the wire or rope B is unwound, the cordG will be wound upon the axle, and drawingdown the eye F upon the wireor rope B, it will keep the track B taut. The sheave O and axle D are soplaced that the level of the point of attachment of the rope shall beabout midway between them. Thus, when the track is raised to the levelof the sheave, it will have a downwardly inclination from the sheave;when the eye F is drawn near to the axle D, the track will have adownwardly inclination ll towards the axle. By means of this alternationthe truck H will be made to traverse the rope by gravity merely ii ineach direction, carrying the weight I, which may, by a cord or otherdevice, he made to disengage itself at any point intermediate betweenthe two points of suspension.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The truck H,in combination with the track B, formed bya wire or ropeadjustably suspended at one end, that its inclination may be reversed,substantially in the manner set forth.

2. The combination of the track B, formed by a wire or rope, the sheaveC, axle 1), eye F, and cord G, arranged to reverse the inclination ofthe track, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

A. W. CRAMER,

Witnesses JNo. Mclurosn,

WM. KIMBLE.

have invented a new and improved Adjustable Track for Conveying Leads byGravity only; and I do hereby that the inclination may be reversed atwill by the-use of mechanism, operatingin the manner now to bedescribed,
